John Terry has been offering to rent out his personal box at Wembley Stadium for £4,000 a game, it was claimed last night.

The latest allegations will add to calls for him to step down as England team captain.

Terry gets a subsidised rate on the 12-seater box as a perk of the England captaincy but rules forbid him from renting it to a third party. It was claimed yesterday that an associate of Terry’s management agents offered investigators use of the box for next month’s England v Egypt friendly. They also allegedly offered to throw in a free signed football shirt.

Anthony White, 35, allegedly told investigators: "It’s John Terry’s box and you can have it. It will be £4,000 and we would want the money in cash."

Last night Terry’s spokesman Phil Hall said the player was not involved. White denied offering the facility in exchange for cash.

The Mirror has also learned that Terry – now earning £170,000 a week – took out new mortgages on his home in Oxshott, Surrey, three times in five years.

Experts suggested it was an unusual way to raise capital. But Bernard Clarke, of the Council of Mortgage Lenders, said: "Getting finance against a mortgage is the cheapest way of borrowing, and for the wealthy with complex financial affairs it could be tax efficient."
